Motor Protection Circuit Breakers (MPCB): Reliable Shield for Your Drives

In industrial and commercial environments, the motor is the heart of the operation. At Solera, we manufacture specialized Motor Protection Circuit Breakers (MPCB) designed to prevent costly downtime and protect your machinery from electrical stress. Whether it's a pump, a fan, or a conveyor system, our protectors ensure your motors run safely and continuously.

Precision Thermal-Magnetic Protection

Our MPCBs provide a dual-action defense system in a single, compact unit. By combining thermal and magnetic protection, we address the two most common threats to motor longevity:

  • Thermal Protection: Prevents damage from sustained overloads by reacting to rising temperatures over time.
  • Magnetic Protection: Triggers an instantaneous trip during short-circuit peaks to isolate the fault immediately.

Specific Models: GM4 & GM6.3

We focus on high-demand small and medium-power drives with two versatile models that cover essential current ranges:

  • GM4 (2.5 – 4 A): Perfect for small motor applications requiring high sensitivity.
  • GM6.3 (4 – 6.3 A): Optimized for medium-duty machinery and industrial equipment.
